T0 all whmt t :mty con/cern:

Be it known that l, Janes H. lavrs, e citizen of the United States, residing at Chicago, in the State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following is a specification. Y

My invention has reference to steam radia tors and has for its principal obiect the provision of means whereby any predetermined portion of such radiator or heating coil can be rendered inoperative by allowing water of condensation to accumulate to the oint de terniined, or a portion of the churn er to be closed to steam, the remainder or' the radiator or coil being permitted to become hea-ted by the removal or the' air and of any Water of condensation which may accumulate above such predetermined'point.

lt is known that in the operation of steam heating apparatus .it is difficult to so moder-` ate and control the heat in a room where oi 'Y one radiator is employed as to get just the right temperature, the radiator' which is fully heated beinbxr oftentimes too hot and if fully shut oil' leaving the room without sullicient heat. It has been heretofore proposed to meet this dilliculty by dividing radiators into difieren? sections or parts say one quarter, one heli or three quarters of the whole, and to provide means lor governing the admission of steam to said parts, and my iiivention has for one ci its objects the provision or" an improved n'icans for accomplishing `uch advantageous results and it is so devised as to secure the accomplishment of such result without any noise or troublesome consequences such have followed some other prior attempts to hold water ol' condensation and steam both in tno radiator at the saine time, and to allow a portion of the loops thereof to become heated without heating: the remainder.

The above, as Well as suoli other objects as may hereinafter appear l attain by means of a construction which l have illustrated in preferred forms in the accompanying dreiving, wherein- Figure 1 is a side elevation showing a radiator with my improvement applied thereto l:

Figure 2 is a sectional view of the preferred apparatus iif'hich l use ior exercising control over the heat in the radiator in carrying out my improvement;

Figure' 3 is a plan view showing theregulat/ing handle and the quadrant or indicating disk therewith and g Figure e is a sectional view line (e) of Figure 2.

Referring to Figures 1 and 2 itwill be Seen that l have in this construction of my invention taken a radiator oi a known form coni posed of sei-,tions joined with connecting pas sages, botli at top and bottoni, and having an inlet or live steam ipe 5 provided with a hand valve 6 the outlet whereof opens into the upper end of the coil or section numbered l, of `the radiator. On the opposite side of the radiator l have arranged an upright valve casing 7 having branch inlets therein S, 99 10, and 11 leading from the radiator section adjacent which is numbered 12, said casing 7 having at its upper end a stelling box 13 through which projects the controlling stern le arranged to be actuated by handle l5 and used for rotation of an inner tube or valve 3() (see Figure 2) which is provided with port openings 8, 9, 10"' and 11u adapted to register with o eiiings to the branch pipes, 8d, 9, ,10d anrljud respectively, but not any two of them at the saine time.

As will be seen by examination of Figure the branch pipes communicate on the inte- .rior ot' the casing 7 with individual chambers, marked respectively 8b, 9b, 10b and 11b, which chambers are separated from the other portions ot the interior o'l the casing 7 by means ol bushings, marked respectively 8, 9, 10 and 11', the valvetube 30 forming a taken on the seat within sai l bushings, and the bushings beingr provided `with the openings which in proper position of tbe valve register with the openings 8, Q, ctc., so as to control the low oi Water produced by condensation through the several branch pipes 8, 9, '10, l1. In the osition shown in Figure 2 the opening 11EL is in register vwith the corresponding opening 11i in the bushing 11C, so that in such position the entire radiator will become heated by the steam and the Water in condensation escape through 'the outlet pipe 31 which if desired may be provided with some forni of tlierniostatlc valve suoli as indicated at 82.

\ ll now itV be desired to sluit olf the lower quarter ot tlieradiator and use only three y quarters ol tho sanic the valve handle 15 is l turned so as to cause the port 10*L to register l l l l will iloiv out through the branch pipe 11 and- IOL with the port d cuttingnof meanwhile the communication between the ports 11 and 111 when water of condensation will collect in the lower end of the radiator up to the opening of the branch pipe -10 after which any further water of condensation will lescape through the branch pipe 10 and down through the center of the tube and out of radiator laterally, that-is as between differ-- ent loops in the same construction there is no chance for leakage of Steam across from one portion to another of this said radiator and interference from the action ofthe waterof condensation. Such water as condenses and collects in the radiator in the sections -whioh are not in use is below the steam and will not interfere with the action of the saine, nor cause aii'y noisy effects as thedrainage of the section in u.-.e is just as -perfect as though there were no water below the branch pipe, which is in open position.

While l have described my invention as applied in conjunction witha system of heating wherein the steam enters at Aone end of the radiator and the 'wa-ter of condensation drains oli' at the other, it is obvious that my iniprovernent is applicable also to a system of heating in which the live steam may arise and be admitted tothe radiator through the vertical casing and sleeve described ascoi-nprising the controlling means governing 4the admission through the branches connecting io the radiator section, the condensation waler passing out through the saine pipe, as is common in single pipe systems in .domestic heating apparatus. lt is also obvious that ii hat the particular system is to Which my invention is applied is inin'iaterial since the essence ol' the improvement resides'in the radiator coiistruction itseli` and the means whereby the several portions thereof are controlled as described above.

Agaving thus described my invention and illustrated its use, what I claim as new, and desire to secure by Letters Patent, is the following:

'1. In' combination, a mainl radiator section, an admission pipe at the top thereof, a

vertical casing which constitutes a drain and comprises aplur'ality of Tsfand connecting pipe sections, a perforated bushing in-the vertical portion of each of lthe T's, passages.

between the horizontal portions of the T's and the -main radiator sec'tionsand having communication with the perfor-(ations in the bushings, and-a -pipeiitting the bushings land provided with perforations out of vertical alinement ladapted to register With-the peri'oi'ations in the bushings', and means tor-'ro-l tating the pipe so that the various vpassages may successively be brought into coni-munication vwith the interiorof the pipe.

2. vIn combination, a radiator section, a drain therefor comprising -av vertical vcasi-ng, a plurality of cross passages to the" radiator section at different heights, -a lplurality of perforated bushings in the casing communieating respectively with the cross passages, and -a rotary pipe fitting the bushings 'and provided with pei'iorations out of vertical alinenient and adapted'to register succes-v' sively with the perforations in the bushings, and means for-rotating 'the pipe so that the f different cross passages may be brought iii-to comi-riunication with the interior of the pipe. ln combination, a radiator section, a drain therefor con'iprising a vertical casing, a plurality ot' perforated bushings in the easing at different heights each 'having communica- Vtion with .the radiator section, and a rotatable pipe provided with perforations out of' Y.vertical 4alinement fitting ythe bushings and adapted at different successive positions 4of rota-tion to permit the registration of its perforationswith the -peifora-tions in the bushings, whereby c(nimunication n'iay be made between the radiator section and theinterio'r of the drain at dill'erent heights.

l testimony whereolI l have hereunder signed my name in the presence of-the -two subscribed witnesses. 1
